Drinking water samples werecollected from 30 stations including residential areas located in the Ergene River Basin in dry (summer) season of 2018.Fluoride levels of water samples were determined by using a spectrophotometer and Cluster Analysis (CA) was applied todetected fluoride data to classify the investigated residential areas according to fluoride contents. Geographic InformationSystem (GIS) was also used to make a visual explanation by presenting a distribution map of fluoride accumulations and alsothe detected data were evaluated in terms of teeth health of local people, who constantly drinks this water. According todetected data, the fluoride accumulations in drinking water of Ergene River Basin were determined between 0.246 ppm(Velimeşe Village) – 1.460 ppm (Bayramlı Village). According to the results of CA, 3 statistically significant clusters wereformed as “High Fluoride Cluster”, “Optimum Fluoride Cluster” and “Low Fluoride Cluster”.en10.22392/actaquatr.644087info:eu-repo/semantics/openAccessArticle162238245369465
